‘Thai Tower’ basil is a very upright Thai basil variety, ideal for pots, herb planters, urban gardens, and small spaces. Its aromatic foliage emits an intense fragrance with spicy, anise, and slightly sweet notes, perfect for enhancing stir-fries, curries, Asian soups, fresh rolls, marinades, and noodle dishes. Its compact and upright growth makes it easy to harvest the leaves while maintaining a well-structured and very decorative plant.

Easy to grow, ‘Thai Tower’ basil prefers a warm and sunny location in fertile, light, and well-drained soil. It performs particularly well in containers on a terrace, balcony, or near the kitchen, where its leaves can be picked as needed. Regular watering, without overwatering, promotes a good production of tender and flavorful foliage. To prolong the harvest, it is recommended to regularly pinch the stems and remove flowers as needed.
